I reimaged my system recently and measured my internet speed on a complete clean system. My ISP declared my fiber to deliver 500 Mbps and I can get even more - 510-530 Mbps.
My OS: Windows 10 Pro x64 1809,
My KTS: 19.0.0.1088 (d)
Unfortunately right after KTS install I'm getting only 80-120 Mbps speed! Nothing else has been modified in the OS, just KTS installed. When I exit KTS and re-measure, I'm getting up to 300 Mbps. It's still far from the full throughput, but much better.
Anyway, it seems clear it's KTS that obstructs the network, however I have no idea how. I've already disabled all (or most) of the settings that might have impacted traffic speed:
injecting javascript to screen pages
limiting traffic at metered connections
screening encrypted connections
auto-detecting proxy
None of those settings has improved my connection speed at all. Does anyone has any ideas what else can be tried?
I remember I did the same test few months back with KTS 2018 and even though the network speed got a bit down (by say 10%) there was no such disaster as with KTS 2019. I'm really thinking on switching into some other security provider...
